Hello
I have opened up the case to a large transformer that converts Input: 120V, 60 HZ, 6A to Output:12V AC, 25A, 300W
I need to convert it to a 20A, 12V DC with 12V minimum requirement.
I measured the output of the transformer with a Multi-Meter and it gave me 12.2VAC with no load
My logic says that it wont work for the following reasons, but I am open to suggestions and clever thinking to make it work.
12.2VAC going thru a bridge rectifier (min Vf of 1.25V) will reduce the voltage to 10.95vDC without a load
With a load (20A x 12v = 240W) I am estimating that my voltage drops to 90% of this value or 10.95 x 0.9 = 9.86v which is not acceptable
The idea is to utilize what I have or scrap it and buy a 12VDC 400W power supply at $28.00
Any suggestions or cheap ideas are very much welcomed....
